A monthly charge of 25 is more attractive to consumers than a one-time charge of 500. Your products will face barriers to entry due to their higher price. 

Stripe Subscription Payment Increase the number of potential customers who can purchase your products by lowering the entry barrier. 

In a pay-once model, you must constantly attract and convert customers to earn revenue. It can be expensive. The investment you made toward customer acquisition can be more difficult to recover if one month's performance is poor.

Your subscribers pay you on a regular basis when they subscribe to your business model. Since the amount of recurring payments is decided on at the time of initial sale, it allows you to predict your revenue each month. Also, you won't order more supplies or stock more inventory than you need.

One-time payment models have a fixed rate of return on your customer acquisition cost (CAC). With the subscription model, however, there is no standard return on this key measure.

Despite the CAC remaining similar (based on marketing channels and conversion paths), the CLV increases with the length of time a user stays with you.

Since you stay in constant communication with your clients, you build trust between them. This makes it easier to market additional and complimentary services. Upsells are usually easier with a subscription business since the customer has a prior relationship with your business and will be receptive to any added value you can provide.

As well, once subscription fees are included in consumers' expected monthly or annual budgets, they are able to see the added benefits as more affordable. This is especially true for customers using your subscription to learn and/or grow, who may find that add-ons enable them to achieve goals more efficiently.
